The distribution of earthquakes within an area will much depend upon what caused the earthquake to happen in the first place. We understand today how earthquakes are caused, and we can record where they happen every day of the year. This has helped us to learn and understand about earthquakes in much detail. We now only miss one important factor that we all would like to know, when and where the next one will be. In truth it must be said that today we are still not close to predicting earthquakes even with all the technology that is available.
